V tively long period when said movement is initiated andrequire butslightexertion to operate the swing.

A further object is to provide an improved construction of swing of thelawn type which is strong and durable in use, which is relatively lightin weight, andneat and attractive in appearance.

With these and other objects in view the invention consists in certainnovel features of construction, and combinations and arrangements ofparts as will; be more fully hereinafter described and pointed out inthe claims. 7 7

In the accompanying drawings- Figure 1 is a view in front elevationillustrating my invention. 7

Fig. 2 is a view in section on the line 22 of Fig. 1.

Fig. 3 is an enlarged fragmentary view in vertical section illustratingby full lines and dotted lines the movement of one of the rockers.

. A represents a supporting frame composed of four uprights 1 preferablyof angle iron connected at their lower ends by base bars 2 extendingboth longitudinally and transversely of the frame and angle plates 3 aresecurely riveted in the corners of the frame providing a strong andrigid structure. Diagonal braces 4 are also provided which are crossedand connect the uprights 1 at the sides of the frame[ 7 Angle bars ,5are secured to the upper ends of and form portions of the frame andthese angle bars 5 constitute rails on which my improved rockers 6 aremounted. The rockers 6 have curved lower edges 7 which are supported onthe horizontal base flanges of the rails 5 and the vertical flanges 8 ofsaid rails prevent lateral movement of the rockers as will more fullyhereinafter appear.

Four vertical hangers 9 are supported by nocKER-swmo.

the rockers 6 and at their lower ends'support a suitable'seat 10. -Rods11- extend through the upper ends of the hangers 9 and through therockers 6 and are secured in place'by'means of nuts 12 screwed onto thethreaded ends of therod's.

Spacing sleeves 13' are positioned on the rods 11 and interposed betweenthe hangers 9 andthe rockers6, and nuts 14 are screwed onto the rodsagainst the inner faces of the hangers to effectually clamp the parts inproper relative position. Below the rods 11 the hangers and rockers areconnected by shorter bolts 15extending through the rockers and thehangers and secured by'nuts 16, and spacing sleeves 17 are provided onthese bolts 15 to hold the hangers and rockers in proper relativepositions.

The upper end of the frame A is strengthened by transversely positionedrods 18 extending through the angle plates 3 at the upper ends of theframe. These rods 18 are positioned parallel to-each other and providedwith spacing sleeves 19;

It will be noted particularly by reference to Figs. 2 and 3, that therods 18 with their spacing sleeves 19 are located inside or within thepair of hangers 9, but spaced from the hangers to allow the necessaryrocking movement of the swing, but limit such movement and preventpossibility of the longitudinal displacement of therookers relative totheir rails 5. d

It will be noted, particularly by reference to Fig. 1, that whileprovide four vertical of theswing requires but slight manual labor and asmooth rocking action is had as friction is reduced to a minimum.

Various slight changes might be made in the general form and arrangementof parts described without departing from the invention, and hence I donot limit myself to the precise details set forth, but considermyhangers 9, these hangers may be, formed by self atliberty to make suchchanges and alv V terations as fairly fall within the spirit and scopeof the appended claims.

claim: r

1. The combination with a supporting frame, a pair of rails at the topof the'frame,

rockers mounted on the rails, hangers susf pended from the rockers, aseat secured to the hangers, a pair of rods located in the pended fromthe rockers, a seat secured to the hangers, said rails composed of angleirons, and rods connecting the rockers above the angle irons andcompelling them to rock in unison. p

In a swing, a frame composed of angle iron bars, strengthening plates atthe angles of the bars, crossed braces connecting the vertical bars ofthe frame, the upper angle bars of the frame constituting rails, rockersmounted on the rails, hangers secured to and spaced from the rockers, aseat'supported by the hangers, rods extending through the upper angleplates, and spacing sleeves on the rods limiting the longitudinalmovement of the rockers. c
